OK. It's possible to configure the server, the high level raid array, and the pool of my old array raid to do : 1/ When the server read/write he do from high level raid 2/ The server make a copie of all data from high level raid to the pool of my old array «when he have the time». But I want this automatics. I don't want this by using something like rsync. What I want to do is make a NFS server with the new high level raid array with primary data. But I want also using my old-low-level raid array to make backup (in case I'm lost my high-level raid array) and only backup. Do you think ZFS can help me ?
